Well, if you don't need anything special like a manifest with the JAR file, all you need to do is put all of your class files and any other files you need into a zip file and then rename its extension to be .jar instead of .zip (that is all a jar file really is).

You may want to read this if you haven't already: http://developer.mozilla.org/en/docs/Building_an_Extension

if read that heres what i do

create new compressed folder (by right-clicking) name it example
then right-click, rename, example.jar

this does not work though, do i need a java developer kit or something installed?
